Non-owner virtual router instances must have a base priority value between 1 and 254. The value 0 is reserved for master termination. The value 255 is reserved for owners. The default base priority for non-owner virtual router instances is the value 100.
The base priority is the starting priority for the VRRP instance. The actual in-use priority for the VRRP instance is determined from the base priority and an optional VRRP priority control policy.
